PACKING FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 254,649, dated March *7, 1882.

' Application tiled September 27, 1881. (No model.l

To all whom it muy concern Be it known that I, JEssE A. HEYDRICK, of Barnharts Mills, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvementin Paekingsfor Oil-Wells; of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this speoilication, in which- Figure l represents the upper portion of a pump, showing my improved well-packing. Fig. 2 is the lower part of the pump, and Fig. 3 is a detail view."

My invention relates to an improvement in oil-pumps; and it consists in certain peculiarities of construction and arrangement relating to the well-packing, as hereinafter described.

In the drawings, A represents the tubing, two sections of which are connected by a screwthreaded thimble, B. The lower end of the tubing A extends to the bottom of the well, Where it is provided-with a plunger, T, which works in the perforated cylinder or barrel X. This barrel rests in the bottom of the well and is connected above to the outer casin g, P M, by means ot' a suitable reducer. As a packer for the casin g I employ the usual rubber collar, H, in connection with the following improved means of increasing its eliiciency: The lower end of the rubber packing is screwed into a thimble, I, until it rests against an interior collar, fi, and the thimble is screwed onto the upper end of the casing M. The upper end of the packer PI is likewise held by means of a thimble, E, which screws onto it, and which, also, by means of an interior threaded collar, is secured to a cylindrical lining, F, to prevent the packer from coming in contact with the interior parts of the pump. The lower end of the lining` F screws into a packer, J, consisting of a collar which is inclosed by the walls of the casin g M.

As stated above, the thimble B is secured to the tubing A, and by means of two quadrantal recesses cut in its lower end, on opposite sides thereof, this thimble is adapted to receive two corresponding projections on the thimble C, whereby the latter and its connections below may be rotated. The lower end of the thim ble C rests upon the interior collar of the thimble E, and is provided with a female thread for receiving the upper end ofa cylinder, Gr. A packer, I), screwing into E at the top, serves to hold C in position. The cylinder G extends below the packer J, where, by means of a reducer., K, it connects with a larger cylinder, L. The cylinder L, near its lower end, is provided on opposite sides with two slots about tive inches in length and one and three-fourths in breadth, through which are made to project the threads of two sections of a cylindrical hollow screw, N, which sections are provided with flanges n, for securing them to a flanged conoidal wedge, 0, which incases the tubing A. That part of the outer casing marked P is provided with an internal screw-thread, into which the screw-sections are to be screwed by turning the tubing A at the top.

As heretofore used the rubber packer H has been made to expand to fill the bore of the well by means of weight applied at the top; but it will be seen that screw-pressure is applied by simply turning the tubing A at the top, whereby the thimble C, the cylinders G and L, and with them the sectional screws N, will be rotated.

When it is desired to remove the packer H from the well the tubing is raised until the knoeker S, secured thereto below the wedge O, shall lift the wedge up through the screwsection N and by means of its flanges the wedge shall draw the screw-sections N inward, until the threads thereof are disengaged from those of the casing P.

The plunger T, which is hollow and provided with a ball-valve, W, near its center, and ports Z, leading to said hollow center through the ball-cageU, is adapted to be set so that its ports Z will register with the ports Y in the barrel X when it is desired to pump oil from the well or to iiood the well after illing the tube A; or by raising the plunger so as to cover the ports in the barrel X, the water in the bottom of the well may be pumped up through the lower part ot' the tubing, which extends to the bottom, and thus through the valves W W2. The ports or perforations in the barrel X may be formed through couplers and between the ends of sections, as shown, or by simply drilling holes through the barrel.

The pump, as above described, will be made the subjeot-matter of a subsequent application.

IOO

With the above construction the packer H will be securely fastened at the ends, so as to insure its being drawn out when desired, and by means of the sectional screws the rubber is made to pack from both ends and more tightly than where weight alone is used. It Will also appear that the well may be easily agitated and flooded by filling the tubing and allowing the fluid to run back into the well through the ports. With this packer and pump all necessary'pumping for a iiowing well can be done with lever or segment, and cog-wheel with 1ever by hand.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1sl 1. In a well-packing, the combination, with the packer H and the tubing A, of' the inter nally-threaded casing P, the screw-sections N, and the conoidal Wedge 0, all arranged and adapted to operate substantially as specied.

2. In a Well-packing, the combination, with the packer H, the tubing A, having knocker S, an outer casing having an internal screwthread, and an inner casing having longitudinal `slots therein, ot' the screw-sections N N and the conoidal wedge O7 adapted to move longitudinally between the said sections, substantially as shown and described.

3. In a well-packing, the combination, with the packer H, the outer casing, M I), and the tubing A, of the thimble B, having two quadrantal recesses in its lower end, and the thimble C, having quadrantal projections on its upper end, whereby the casing L G may be rotated, as shown and described.

4. In a well-packing, the combination, with the packer H, the outer casing, M P, and the tubing A, of the thimble E, screwing on the said packer, the lining F, the thimble C, held in engagement with the thimbleE by the packer D, and the thimble B, screwed on the said tubing and meshing with thimble G,substantia1ly as shown and described.
